"But, in this territory lies the great valley of the Mississippi, now the real, and soon to be the acknowledged, seat of empire of the world. The sway of that valley will be as great as ever the Nile knew in the earlier ages of mankind. We own the most of it. The most valuable part of it belongs to us now; and, although those who have settled above us are now opposed to us, another generation will tell a different tale. They are ours by all the laws of nature; slave labor will go over every foot of this great valley where it will be found profitable to use it; and some of those who may not use it are soon to be united with us by such ties as will make us one and inseparable. The iron horse will soon be clattering over the sunny plains of the South, to bear the products of its upper tributaries to our Atlantic ports, as it now does through the ice-bound North. There is the great Mississippi, a bond of union made by Nature herself. She will maintain it forever." * * * * * "In all social systems, there must be a class to do the menial duties, to perform the drudgery of life--that is, a class requiring but a low order of intellect and but little skill. Its requisites are vigor, docility, fidelity. Such a class you must have, or you would not have that other class which leads progress, civilization, and refinement. It constitutes the very mud-sill of society and of political government; and you might as well attempt to build a house in the air, as to build either the one or the other, except on this mud-sill. Fortunately for the South, she found a race adapted to that purpose to her hand--a race inferior to her own, but eminently qualified, in temper, in vigor, in docility, in capacity, to stand the climate to answer all her purposes. We use them for our purpose, and call them slaves. We found them slaves, by the 'common consent of mankind,' which, according to Cicero, '_lex naturæ est_'--the highest proof of what is Nature's law. We are old-fashioned at the South yet; it is a word discarded now by 'ears polite;' I will not characterize that class at the North with that term; but you have it; it is there; it is everywhere; it is eternal." Upon going home to his South Carolina plantation, a change seems to have come over the mind of the senator--or he was greatly misunderstood while at Washington. In a speech, delivered at Brownwell Court House, South Carolina, October 27, 1858, he astonished some of his neighbors as well as distant friends and enemies, by the enunciation of peculiarly moderate views for a South Carolina Democrat. Let us quote a few paragraphs. First upon Disunion. Says Senator Hammond:
